Note that an object count appears in each blister window as an integer, for
one–color applications such as tablets, or as a number and decimal fraction,
for two–color applications such as capsules. In the both cases, the reported
object count should correspond to the actual number of objects in the blister.
In the second case, however, the count may contain a decimal fraction such
as “3.5.” This indicates that, for some reason, only half of an object was
detected, and the object count is therefore either too high or too low.
At this same time, the help message box displays the following message:
The system is about to learn the nominal object
positions. Verify that each window contains the
correct number of objects. If not, adjust the
Min. Area setting.
If any of the object counts are incorrect, use the Min. Area slide bar to adjust
the minimum acceptable area for all objects. Initially, the Min. Area value
reflects the default setting of 25 pixels in the Adjust
→
Define Objects
→
Define Tolerances
→
Min. Area menu item.
If any object count is too low, slide the cursor up to increase the Min. Area
value to the point where all object counts are correct. Conversely, if any
object count is too high, slide the cursor down until all object counts are
correct.
NOTE: During inspection operations, the system will ignore any object
whose area is less than the
Min. Area setting. The purpose of this is to
eliminate false rejects caused by small reflections that may appear to be part
of a broken tablet, but are not. Do not set the
Min. Area too high, however,
or the system may not detect small fragments of broken tablets.
When you have verified that all object counts are correct, press Continue to
teach the system the nominal object positions and go to the next step.
Perform Teach–in
When you pick Continue , the system learns the nominal object positions.
If the number of sample images specified in the Configure
→
Teach Count
menu item is 0, the auto setup will be completed at this point, and the
following message will appear in the message box:
Auto–setup is complete. Select Exit to return
to run mode.
In this case, since no part teaching is performed, during run operations the
system will use the minimum position, area, and shape tolerances that you
specified in the
Configure menu.
